Abstract

Bei einem Verfahren oder einer Vorrichtung zur Bearbeitung einer Faserstoffbahn oder einer Fasern enthaltenden Suspensionsschicht (12) bei der Herstellung einer Faserstoffbahn wird die Faserorientierung in der Suspensionsschicht oder in der Faserstoffbahn durch wenigstens ein Schallfeld (25) beeinflusst, dem die Suspensionsschicht (12) oder die Faserstoffbahn ausgesetzt wird.

Figure imgaf001
In a method or a device for processing a fibrous web or a fiber-containing suspension layer (12) in the production of a fibrous web, the fiber orientation in the suspension layer or in the fibrous web is influenced by at least one sound field (25) to which the suspension layer (12) or the Fiber web is exposed.
